There is a module file_monitor.erl that currently lives in the EUnit
repository (I've been meaning to put it somewhere more suitable and
make it more official, but that hasn't happened yet). It currently
only does polling - so it's portable at least - and it has no builtin
function for monitoring a whole tree, so you have to do the traversal
yourself to monitor subdirectories.
